Review: JDS Labs O2 (Black edition) + O2/ODAC discussion - Page 7

Well, spent a good amount of time with the O2.  Tried various phones as well as different sources including the Behringer UCA202 to give the O2 some Foobar love.  For the most part portable sources were my go to.  The last few months I have been really interested in battery powered amps with a bit larger footprint than the traditional portable amps.  I still love the desktops though, but trying out new things keeps it real.

The phones I was most interested in trying with the O2 were the D5000s.  The O2 tightened everything up nicely with no bass bloat while retaining that sexy, smooth Denon love.  I listen to a variety of music- rock, metal, dubstep, house, trance, hip etc. and the combo delivered.  Very clean and clear.

I guess I can touch up on this without breaking any rules..lol.....---  For those newer members, the designer of this amp used to be a member.  Many head-fiers sparred with him on some of his claims on a certain 'thread', myself included (all in good fun of course..).  Back and forth we all went...lol...

Well, all I have to say is that the wavman talked the talk and he walked the walk in designing a great amp.

Cheers!!!

Gotta get ready for the Heat game and a little Youthanasia always gets the juices pumping....

Great..glad its working out good for you!

KP the O2 would be perfect as a transportable for your laptop

I got one this past Monday. It is indeed a perfect laptop amp. It's small enough to still be easy to carry, but it has enough power to handle full size cans. The original intent was to drive DT990's or K550's at the office and T1's when I used my laptop in front of the TV. 

As it turned out, it did such an excellent job on the T1's I found myself taking the Beyers into the office all week. $150 dollar amp on $1200 'phones. Heh. I don't think I can bring myself to throw the T1's into my laptop bag for travel, but it is tempting.

Source from laptop is HRT MS II, FLAC, JRiver WSAPI Event, no DSP.

Build quality is excellent, which is what was expected after receiving a C421 earlier this year from JDS. Do wish the cover to get to the 9V batteries did not require screw driver to remove, as it'd be nice to be able to easily drop a couple of non-rechargeable batteries in there in a pinch.

It drives my LCD2 just wonderfully....as well as AKG Q701's,,,,,

By a happy coincidence, the AC plug on the O2 is the same as the one for my Asus laptop. Carrying charger for O2 is now optional. Yay.

Even if the plug is the same, how does this alleviate the need to carry the other wallwart?  It's not like the laptop AC/DC adapter (well, it's a SMPS) outputs AC for the O2.

Make sure its a AC adapter not a AC to DC adpapter! 

Alex

It outputs 19V AC so it is within the power range suggested at JDS.
